The movement features automatic beat adjustment and a maintaining power mechanism to provide secondary power while the clock is being rewound.

The movement has three drive weights - these provide power to the Strike, Pendulum and Chimes.

There are two control levers - the lever on the left provides the selection of Silent, Automatic Night Silencing between 22:00 and 07:15 or Continuos Striking. The lever on the right contols the Westminster chimes.
